很多人長(zhǎng)時(shí)間操作電腦后揉著酸痛的手臂，于是想能否發(fā)明一種可以脫離桌面自由移動(dòng)，又不改變使用習(xí)慣的無(wú)線鼠標(biāo)。從而達(dá)到即能方便操作現(xiàn)有軟件又能解除使用者的疲勞，擴(kuò)大使用范圍的目的。
通過(guò)觀察機(jī)械陀螺儀獲得靈感，經(jīng)過(guò)反復(fù)試驗(yàn)和四代作品改進(jìn)，利用重力和慣性原理制作了內(nèi)置萬(wàn)向節(jié)支撐的偏重心球殼體，固定在光電掃描鼠標(biāo)之下。工作時(shí)手腕向需要方向轉(zhuǎn)動(dòng)，光電頭與方向固定的球平面產(chǎn)生相對(duì)位移，將鼠標(biāo)對(duì)桌平面掃描變?yōu)閷?duì)球面掃描，輸出位移信息，從而實(shí)現(xiàn)脫離桌面自由使用。
本離桌式鼠標(biāo)既可支撐使用亦可懸空使用大大減輕使用疲勞。除用于辦公、教學(xué)，娛樂(lè)外，特別適合臥床，坐沙發(fā)等休閑及特殊場(chǎng)合使用。制作成本低廉，適合推廣。
Free mouse
Computer Sciences

The purpose of this project is to invent a kind of mouse that can be used freely without the fixed support such as a table, so that it may be applied in more jobs and reduce the users’ fatigue. Its main characters are low cost, acceptable to more people without changing their former habits when using it.
There are two ways in making this kind of mouse. One is to alter the former cursor that scans a fixed plane into one that scans a ball surface which moves together with it. The “universal axis” that is particularly designed supports the aberrant-barycenter ball which is fixed under the cursor. The cursor, via the human hand, will obtain relative displacement away from the ball surface, thus realizes the operation of the mouse. The other way involves aberrant-barycenter wheels, which are stalled vertically, and a mechanical electronic mouse raster axis. The two devices are connected through a rate changeable riving system. With the help of human hand, the relatively stationary wheel drives the raster to operate.
Considering the time, the free mouse designed by above first method operates easy and accurate. It can be used with or without a fixed support. For example, we can use it either dependently e.g. at work, for drawing and games, or independently such as in sofa, bed or for multi-media display. What’s more, the users need no special training in order to manage it freely with no trouble. Therefore, it may greatly reduce the users’ fatigue caused by long time work.
